extracting using WINRAR

Hi everyone. this is what I have been doing. I have downloaded a trial of WINRAR. I created by target folder first c/program files/new program. I have a folder with 7 winrar files to be extracted. I click on all the winrar files and right click and hit extract to. I choose the new folder i created. It seems to extract. problem is when i go to the new folder its empty. I try it again and asks if i want to over rights 'existing files'?? i choose yes but again the folder remains empty.

thanks for comments, I ended up extracting to same location and then installing program where I wanted it. Interesting on my laptop the one file bacame an ISO file which i could then mount but on the desktop, which is a bit older the icon remained as WINRAR. its only when to winrar properties that i found it was a iso file, so that through me a bit,
